STRUCT VCNL3020_DATA(9)

✨ struct vcnl3020_data(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is literally a struct tour, no cap 💅. It's the struct vcnl3020_data page — like, all the little fields that hold the vcnl3020's whole personality. Let's get into it 🫶

---

🌸 NAME 🌸

struct vcnl3020_data — vcnl3020 specific data. that's it, that's the vibe ✨

---

🦋 SYNOPSIS 🦋

here's the whole thing in all its glory, character for character, don't touch a single brace 🎀

struct vcnl3020_data {
    struct regmap *regmap;
    struct device *dev;
    u8 rev;
    struct mutex lock;
    __be16 buf;
};

👑 Members 👑

okay these are the main characters, one by one 💖

• regmap — the device register map. yes, THE map. the register-y one 🗺️
• dev — the vcnl3020 device itself. iconic, obviously 👑
• rev — the revision id. it's giving "which version are we on" energy ⭐
• lock — a lock whose whole job is protecting access to the device hardware registers. do not skip the lock, bestie, that's a whole mess waiting to happen 🔒💀
• buf — a __be16 buffer. big-endian, sixteen bits, living its truth 🌈

---

🌟 SEE ALSO 🌟

• Kernel file ./drivers/iio/proximity/vcnl3020.c — the actual source, go read it iykyk 📖
• struct vcnl3020_property(9) — the sibling page, say hi for me 🫶

---

ngl the lock one is the one to remember fr fr — hardware registers don't protect themselves 💅

and that's the page!! mwah 💋 this one came out of ./drivers/iio/proximity, dated October 2026, and it's filed under struct vcnl3020_data(9) — slay, go forth and be knowledgeable about sensors 🧚‍♀️🌸💜
